To all whom it may concern.-

Be it known that I, HENRY O. SHOLDEBRAND, a citizen of the United Statesof America, residing at Salt Lake City, in the county of Salt Lake andState of Utah, have invented new and useful Improvements inStevepipe-Cleaners, of which the following is a specification.

This invention relates to stovepipe cleaners, the object of theinvention being to provide a cleaning device which may be readily andconveniently constructed from a single piece of wire, and which iseffective in use and adapted to be inexpensively manufactured.

A further object is to provide a novel construction of pipe providedwith a guideway for the operating member of the cleaner. 7

In the accompanying drawings,Figure 1 is a longitudinal section inperspective of a joint of pipe embodying my invention. Fig. 2 is afragmentary perspective looking toward the side of the same on which theguide is formed. Fig. 3 is a vertical longitudinal section through aflared joint of pipe, and shows a modified form of the invention. Fig. 4is a section on the line 44 of Fig. 3. Fig. 5 is a longitudinal sectionthrough an elbow and a form of cleaner used in connection therewith.Fig. 6 is a section on the line 6-6 of Fig. 5. i

The joints and elbows in which the improved cleaning devices areemployed are each formed with a guide for the shank or operating memberof the cleaning device. This guide is formed in line with and betweenthe terminals of the seam 2. The guide may be of any length to secure adesired range of movement of the cleaner and is formed by transverselyslitting the pipe, as indicated at 3, at distances apart accordingto'the length of the guide to be formed, bending the meeting side edges4 of the pipe at an outward angle in divergent relation, and finallybending the extreme portions of the edges inwardly and overlapping andriveting them or otherwise seeming them together, as indicated at 5. Theguide thus produced extends longitudinally of the pipe between portionsof the seam and is approximately of triangular form in cross section,the narrower end thereof communicating with a slot 6 connecting theguide with the interior of the pipe and formed by the outbending of theportions 4.

The cleaner is formed from a single piece of wire, one end of the wirebeing bent to provide a terminal loop, coil or ring 7, thence continuingto form an arm 8, bent to form an intermediate coil 9, thence bent toform an arm 10 lying in line with the arm 8, and again bent to form acoil 11 constituting another terminal coil, the coils being arranged inalinement with each other and connected by the intermediate arms 8 and10. In the form disclosed in Fig. 1 the wire continues from the coil 11,being bent or offset beyond said coil, as indicated at 12, to projectoutwardly through the slot 6 and thence projects parallel with the axisof the coils to form a shank 13 extending longitudinally within theguide. The wire continues from the shank in form of a handle 14projecting beyond the guide and having a terminal grip 15. At the pointof junction of the shank and handle an offset or shoulder 16 is formedto bear with a desired pressure upon the outer wall of the guideway tonormally hold the cleaner, when arranged in a vertical pipe, frommovement. The coils 7, 9 and 11 conform in diameter to the interiordiameter of the pipe, and it will be understood that by grasping thehandle 15 and imparting a reciprocatory motion to the cleaner the coilswill scrape the pipe and loosen the soot therefrom, so that the loosenedsoot will be carried off by the draft or may be removed by disconnectingan elbow or one of the pipe sections.

In the embodiment of the invention shown in Figs. 3 and 4, the pipesection I is of flaring form, such as is commonly used as the basesection of a pipe to connect directly with a stove, and the coils 7 9,11, are of flaring form to conform to the shape thereof. In thisconstruction the shank 13 is mounted within the guide and serves solelyas a guiding member, a loop I?) being formed at its point of junctionwith the coil 11 so as to admit of its engagement by the hooked end 16of a poker or suitable tool whereby the cleaner may be operated.

In the constructions shown in Figs. 5 and 6 I have shown the applicationof the invention to an elbow l,

of the same construction as that shown in Fig. 1, but With the coils 79", 11, arranged so as to impart a longitudinal curvature to the cleanerto conform substantially to the degree of curvature of the elbow, sothat the cleaner will operate effectually therein.

Having thus described the invention, what is claimed as new, is:-

A stovepipe cleaner comprising a single length of wire bent to formterminal and intermediate coils and arms connecting the respectiveterminal coils with the intermediate coil, said arms being arranged atright angles to the coils and in allnement with each other and parallelwith the axis of the cleaner, the wire being continued from one of theterminal coils to form an operating handle.

In testimony whereof, I atlix my signature in presence of two witnesses.
